【摘要】在镁铝系合金中添加MgCO3后,由于生成了大量的弥散的Al4C3颗粒,使得晶粒变细晶界增多,因而使合金中变形晶粒中位错在晶界处受阻,从而使合金的强度提高。更多还原

【Abstract】 After adding MgCO3 in the magnesiumaluminum series alloys,the grain of alloys had turned refiner and the grain boundary had turned more becuse of producing plentiful dispersive particle of Al4C3,accordingly the dislocation in the transmutative grain in the alloys had been prevented at the grain boundary,thereby the intensity of alloys had been improved.更多还原
