pre-deformation prior to overaging remarkably refine and spheroidize the grain structure of aa2195 al-li alloy.
过时效前的轧制预变形明显细化并等轴化aa2195铝锂合金的晶粒。
when overaging temperature is over 300 ℃, martensite is decomposed into carbide, which is harmful to mechanical properties of dual phase steels.
当过时效温度大于300 ℃,马氏体分解,碳化物颗粒析出,将对双相钢性能产生不良影响。
as the overaging temperature in the sppt increasing, the strength of 2024 alloy also improving. when the over-aging temperature obtains 350℃, the alloy performance is superior.
