Formation of Mg2Si-10vol%Al Composite Via Solid-State Reaction

摘要：

　　Mechanical milling effects on the formation of Mg2Si-based composite toughened by Al in-situ via solid-state reaction were investigated.The results indicated that,during annealing,the growth of nano-Mg2Si grain has two obvious stages,the slow growth stage at low temperature (190℃ < T < 400℃) and the rapid growth stage at high temperature (400℃ <T<600℃).With the increase of annealing temperature,the ratio of the formation of Mg2Si increases and the microstrain decreases.Mechanical milling could promote the formation of Mg2Si and lower the formation temperature.The reaction temperature of powders milled for 50 h decreased nearly 350℃ than that of the unmilled powders.
