【摘要】 研究了变形温度和变形程度对铸态AZ31镁合金组织和性能的影响。结果表明,在变形程度一定时,随着变形温度的升高,晶粒有长大的趋势;而在变形温度一定时,随着变形程度的增大,再结晶程度增加(ε=2.87时已全为再结晶组织),晶粒越细化,分布也越均匀;抗拉强度增量开始是逐渐增大的,但到一定程度时则出现峰值,以后不再增加。更多还原

【Abstract】 The influnce of deformation temperature and deformation etent on as - cast structure of AZ31 magnesium alloy are studied, show as a result,when deformation is certain,grains have tendency to grow large along with the increacement of deformation temperature;And when deformation extent(ε= 2.87 already is that recrystallization structure completely),the finer grain is,the more homogeneous distrabution is;It is increased gradually that the increment of tensile strength begin,but when going to certain level,arise peak value,not increase afterwards again.更多还原
