    摘要
  • 摘要: 采用應力松弛方法,研究了Ll2型結構Al3Ti(+9.7Fe)合金形變過程中形變誘導析出Al2Ti沉淀相的現象,發現Al2Ti析出是合金室,中溫下表現為它是脆性斷裂的主要原因。用TEM方法,研究了Al2Ti析出相與Ll2型基體的位向關系,表明Al2Ti的慣析面為{100}面。

     

    Abstract: The precipitaion of Al2Ti induced by strain was studied by means of stress-relax method during deformation of Ll2 structure Al3Ti(+9.7Fe) alloy.It is shown that the Al2Ti precipitatings is the principal reason for the ductile fracture of Al3Ti base alloy at room or middle temperature.By TEM,it is proved that the Al2Ti precipitation has rigorous crystal orientation relationship with Al3Ti matrix,{100}p//{100}m.
