The J-20 already showed blue flame but that's not a good indicator. Al-31 has blue flame and the F119 has orange-red flame, doesn't mean the Al-31 works at higher temp than the F119.

A Chinese team apparently made a breakthrough in producing a new alloy for engine blades that significantly pushes performance boundaries at higher operating temperatures... Below is the abstract of the paper the team has published in Journal Nature:
Polysynthetic twinned TiAl single crystals for high-temperature applications
TiAl alloys are lightweight, show decent corrosion resistance and have good mechanical properties at elevated temperatures, making them appealing for high-temperature applications. However, polysynthetic twinned TiAl single crystals fabricated by crystal-seeding methods face substantial challenges, and their service temperatures cannot be raised further. Here we report that Ti–45Al–8Nb single crystals with controlled lamellar orientations can be fabricated by directional solidification without the use of complex seeding methods. Samples with 0° lamellar orientation exhibit an average room temperature tensile ductility of 6.9% and a yield strength of 708 MPa, with a failure strength of 978MPa due to the formation of extensive nanotwins during plastic deformation. At 900°C yield strength remains high at 637MPa, with 8.1% ductility and superior creep resistance. Thus, this TiAl single-crystal alloy could provide expanded opportunities for higher-temperature applications, such as in aeronautics and aerospace.

background
Since the successful development of nickel-based alloys, turbine engine applications in the aviation sector has been greatly promoted. By improving and developing nickel-based superalloy and titanium-based alloys, and advanced manufacturing technology, aerospace engine performance applications has been constantly improved. However, with thrust-weight ratio and the continuous improvement of turbine tip temperature (Table 1), a turbine engine compressor and turbine stages gradually reduced, single-stage load is increasing, more and more high stress level part, increasingly harsh conditions, blades and other critical parts of the structure are also increasingly complex, has two main traditional high-temperature structural materials performance nickel-based alloys and titanium-based superalloy increased to its limit level, it is necessary to seek more advanced and reliable materials and processes designed to meet the future requirements of the engine.
γ-TiAl based alloy having excellent high temperature strength, creep resistance, oxidation resistance and flame retardance, and low density, high modulus of elasticity (Table 2), the comprehensive performance is better than the conventional stainless steel and nickel-based superalloys, etc. the toughness was higher than conventional ceramic materials. In addition, the coefficient of expansion of aluminum alloy titanium nickel-based alloys can be compared with a low coefficient of expansion, and also below the flammability of nickel-based alloys. These advantages make it the aviation, aerospace, flight missile engines and heat-resistant lightweight structural parts of the car's most competitive materials.
Situation TiAl Alloy
TiAl based alloys are currently the greatest obstacle to the practical application of such hand is brittle at room temperature alloys, difficult deformation processing, the other is insufficient oxidation resistance above 850 ℃, which restricts the application and promotion of TiAl based alloy. In the near future to develop the high-Nb-TiAl based intermetallic compounds in high-temperature strength and oxidation resistance has made great progress, a high melting point component of Nb increases the temperature of the alloy melting point and ordered, so that the use of alloys the temperature reaches 900 ℃ or more, so that the system has the potential to replace the alloy exhibits a nickel-based alloy. However, high-niobium alloy at room temperature and greatly improve the high temperature strength of TiAl alloys, but also further reduces its temperature and high-temperature ductility, especially high temperature ductility lower than the average TiAl based alloys.
Since the 1990s, researchers of the world regarded the thermoplastic processing technology research and development as a research focus TiAl based alloy, TiAl based alloys have long thermoplastic processing and related field is very active. Large deformation of TiAl alloy weight thermoplastic processing, can significantly improve the room temperature ductility TiAl alloy and plastic working through forging billet after due with a fine and uniform microstructure, it is possible to further meet the needs of isothermal forging. Been to thermoplastic processing TiAl alloys, through a certain heat treatment process, you can get a variety of comprehensive performance, to meet the engineering application.
US company GE will cast a full set of 98 low-pressure turbine blades mounted on a large commercial transport aircraft CF6-80C2 engine, through the assessment test 1000 flight cycles. Thyssen (Thyssen) and Rolls-Royce (Rolls-Royce) forging a successful engine high pressure compressor blades, alloy composition used is Ti47Al3.7 (Nb, Cr, Mn, Si) 0.5B; Japan's Mitsubishi Corporation adopted package sets of forging a Ti-42Al-10V alloy blades, the alloy has good high temperature plastic, the company also developed Ti42Al5Mn alloy, and the use of forged the way to create a machining turbine blades and other parts; use Rolls-Royce alloy TNB Department produced a high-pressure compressor blades and vanes will be delivered this engine assembly for testing.
TiAl Alloy Development Trend
Titanium aluminum alloys for aerospace materials showing remarkable development prospects, become an advanced military aircraft engine high pressure compressor and low pressure turbine blade material of choice. GE's GE90 engine program titanium aluminum alloy blades used in place of nickel-based alloys, will reduce engine weight of 200 to 300 kg or more. Airbus and Boeing are working to increase engine thrust than the low-pressure turbine maximum weight loss potential in the near future the rear of the turbine rotor blade titanium aluminum alloy blades. Analysis showed that the future engine of the market demand for γ-TiAl low pressure turbine blades of up to one million, will replace the current advanced turbine engines last a heavier nickel-based blades. NASA reports that by 2020 the amount of titanium and aluminum alloy composites in aviation, aerospace engines will share at about 20%.

Let's stop the personal stuff. We're all guilty of some of it, so I'm not blaming anyone in specific. Let's just end it.
As for material advances, let's see what difference they make with China engine development, if any. When China start mass producing engines on par with US manufacturers, then the Peanut Gallery will believe.
