【摘要】 采用粘结技术制备出了性能良好的磁致伸缩复合材料,着重研究了合金含量、粉末粒度、磁场取向、粉末表面处理对样品的静态弹性模量及抗压强度的影响规律。结果表明,粉末粒度、粉末表面处理对复合材料的抗压强度及静态弹性模量均有较大的影响;合金含量、磁场取向对复合材料的静态弹性模量影响不大,其中合金含量对复合材料的抗压强度有较大的影响。更多还原

【Abstract】 Adopting bonding technology, the giant magnetostrictive composites have been prepared. The effects of preparation conditions, such as powder composition, powder size, magnetic field orientation and powder surface treatment, on the static elastic modulus and compressive strength for the giant magnetostrictive composites have been investigated in this paper. It is found that the powder size and the powder surface treatment have obvious effects on the static elastic modulus and compressive strength, and few effect for the powder composition and the magnetic field orientation, but the powder composition has effects on the static elastic modulus.更多还原
