硬度

The results show that these semi-high speed steels can be hardened remarkably by secondary hardening to meet the hardness requirements of cold rolling. The secondary hardness of the tested steels is increased with the contents of alloying elements such as Mo, V, Si and changed with quenching temperature to show two peaks.

The hardness and wear resistance increase with increasing TiB2 content. Adding about 1.5%Mg in melt restrains the conglobation of the TiB2 particles, which makes the size of TiB2 particle decrease and the distribution of TiB2 particle is more homogeneous. The strengthening effect of TiB2 particles is enhanced and the hardness and wear resistance of composites are obviously improved. The excess Mg decreases the refinement effect of TiB2 particles, but the hardness and wear resistance are improved continuously.

结果表明：反应生成的TiB2颗粒平均尺寸约为0.5 μm，材料的硬度和耐磨性随着TiB2含量的增加而提高；添加1.5%Mg元素可明显细化TiB2颗粒，且使其分布更加均匀，增强TiB2颗粒的弥散强化和细晶强化效果，复合材料的硬度和耐磨性显著改善；过量的Mg元素(3%)会造成TiB2颗粒细化效果的下降，但其硬度和耐磨性能继续得到改善。

Silica and alumina, to an organic silicone rubber, ShoreA 70, to improve the hardness of silicone rubber material and the results indicated that the addition of silica improved the hardness of the material dramatically, but depressed the heat-resistance markedly; the addition of alumina improved the hardness of the material also, but more loading was needed to achieved the hardness as compared with the silica added materials.

研究发现，添加气相法白碳黑能显著提高硅橡胶的硬度，但使硅橡胶的耐热老化性能明显变差；氧化铝也可以用于提高硅橡胶的硬度，但与气相法白碳黑相比，达到相同硬度时的添加量要大的多；比较而言，通过添加氧化铝获得的高硬度硅橡胶具有较好的综合性能，更能满足电化铝烫印版的制作需要。

Adding transition metals into the TiN films by arc ion plating (1) The hardnesses of theN films are higher that that of the TiN films, proving that the alloy hardening effect is a common phenomenon;(2) The structures of the alloyed films are determined by the added element properties such as covalent radius, electro negativity, free energy and lattice parameters of the MN compound;(3) theN film consists of a mixture of multi phases with high hardness but quite brittle, while the other MN films are composed of single phase with the fcc TiN structure and their hardesses, functions of the added amounts of the elements, manifest always a maximum at a certain M percentage.

一、将过渡金属M用电弧离子镀方法添加于TiN薄膜中：1。N薄膜硬度均高于TiN薄膜硬度，合金强化效应普遍存在；2。薄膜相结构决定于添加元素M的周期律信息，包括M的共价半径、电负性，及MN化合物的自由能、晶格常数等；3。N为多相混合结构，薄膜硬度高，但韧性差；其它N的相结构为TiN类型的单一fcc结构，薄膜硬度随M添加量变化并出现峰值；4。
