雾化喷射沉积成型2014铝合金＋15％SiCp（体积分数）和18Ni（250）马氏体时效钢＋10％（Al2O3）p（体积分数）金属基复合材料表现出加速时效行为.采用显微力学探针技术研究了复合材料的时效行为，发现在增强颗粒附近存在明显的弹性模量和硬度的梯度分布，是热错配应力造成的位错密度分布引起的析出相梯度分布的结果.该项结果为更精确地预测时效硬化型合金为基的金属基复合材料的时效行为提供了依据.
Atomization spray deposition Accelerated aging behavior of 2014 aluminum alloy with + 15% SiCp (volume fraction) and 18Ni (250) martensitic steel + 10% (Al2O3) p (volume fraction) Aging technique was used to study the aging behavior of composites. It is found that there is a gradient distribution of elastic modulus and hardness in the vicinity of the enhanced particles, which is the result of the gradient distribution of precipitated phases caused by the dislocation density distribution caused by thermal mismatch stress This provides a basis for predicting the aging behavior of the age-hardening alloy-based metal matrix composites.
