摘要

研究了普通烧结铁氧体、热压铁氧体和热等静压铁氧体的显微结构和相组成对样品抗折强度、显微硬度、热膨胀系数的影响及其机理。实验表明

热等静压铁氧体具有很好的磁性和力学性能

是一种优良的磁头材料。

Abstract

The dependence of the microstructure and phase composition of the conventional sintered

hot-pressed （HP） and hot isostatic pressed （HIP） ferrites on the bending strength σ（?） vickers hardness Hv and coefficient of thermal expansion has been studied

its mechanism has also been discussed.The results show that HIP ferrites have an improved mechanical properties and such ferrites are very good magnetic head materials for high density recording.
