| 摘 要： | 采用工业挤压机研究了挤压比和挤压温度对AZ31镁合金织构的影响.结果表明,在相同的挤压温度下,随挤压比增加,以{01(-1)0}面织构为代表的变形织构由强到弱;而以{06(-6)1}、{02(-2)1}面为代表的再结晶织构由弱到强.主要织构组分在挤压比为16处形成拐点,形变织构降至最低,随后再结晶织构逐渐增强,表明在拐点附近再结晶完成.挤压比相同时,低温度变形的织构组分以{01(-1)0}面形变纤维织构为主.当挤出温度增至258℃时,达到完全动态再结晶,温度再增高将形成高漫散度的{01(-1)0}再结晶织构.

| Abstract: | The effect of the influence of extrusion ratio and extrusion temperature on the texture of AZ31 magnesium alloy is studied using a industrial extrusion machine.The results show that the deformation textures represented by {0110} surface texture decreases.With the extrusion ratio increasing,the recrystalization texture of {0661} and {0221} increases.The main texture components have a inflexion when the extrusion ratio reaches 16,which is a minimum in deformation texture and then recrystal texture increase gr... |
