日本东洋铝公司开发了一种弹性钛—铝合金,它金可用于制造机器和汽车零件,如阀和涡轮机转子。 在600℃时,这种模制材料的杨氏模量达到159GPa,为钛合金的两倍。它能耐800℃高温,并且在高温下不变形。铝的强度在温度超过300℃后开始下降。而陶瓷虽然耐热,但其弹性差。 粉末混合料由直径几十微米的钛粉与等体积相同粒度的铝粉构成。使用时,这种粉末料与有机粘结剂混合,在温度高于1000℃烧结。通过高温清除粘结剂,成品由直径10~100μm微粒构成,其中铝和钛按原子能级规则排列。
Japan’s Toyo Aluminum has developed a flexible titanium-aluminum alloy that can be used to make machines and automotive parts such as valves and turbine rotors. At 600 ° C, the Young’s modulus of this molded material reached 159 GPa, twice that of titanium alloys. It can withstand 800 ℃ high temperature, and does not deform at high temperature. The strength of aluminum starts to drop after the temperature exceeds 300 ° C. Although the heat-resistant ceramic, but its flexibility is poor. Powder mixture from the diameter of tens of microns of titanium powder and the same volume of aluminum particles of the same size composition. When used, this powder material is mixed with an organic binder and sintered at temperatures above 1000 ° C. By removing the binder at elevated temperatures, the finished product consists of particles of 10 to 100 μm in diameter, with aluminum and titanium regularly arranged at the atomic level.
