查询词典 hardness

The results showed that the hardness of CGHAZ is decreasing,bainite ferrite strip coarsens,the shape of M－A constituents transforms strip into block,its size becomes large,and its bulk extends, with increasing of t8/5.In addition austenitic,M－A constituents in γ grain boundary coarsens and manifolds with increasing of t8/5.They all deteriorate the toughness of pipeline.And the extended zone of impact fracture shows brittle.

结果表明，随着t8/5的增加，粗晶区硬度逐渐减小，贝氏体化铁素体粗化，且其间的M－A组元由条状转变为块状，平均弦长增加，体积分数增大，奥氏体晶界M－A组元增多变粗，管线钢的韧性恶化，抗裂性变差，冲击断口扩展区呈脆性断裂。

There is only one thing that He always condemns: hardness of heart.

一直谴责的只有一件事情∶心硬。

The density, electrical contact resistance and hardness of these two alloys were tested. The results show that Ag and rare earth oxide appear in Ag-Y and Ag-Ce alloy after internal oxidation. The distribution of oxide particles is inhomogeneous and seriously conglomerated in Ag-Y2O3 and Ag-CeO2 sintered bulk, but they are dispersed and uniform in Ag matrix after severe plastic deformation. The relative densities of wire materials are larger than 99% and the electrical contact resistances are low (＜2.2 μΩcm).

结果表明：Ag-Y和Ag-Ce合金粉末经内氧化处理后生成Ag和稀土氧化物2种物相；Ag-Y2O3和Ag-CeO2材料烧结坯中氧化物颗粒分布不均匀且团聚严重，但材料经过大变形加工后，氧化物颗粒细小，均匀地弥散分布在银基体上；最终产品丝材的相对密度均达到99%以上，电阻率较低(＜2.2 μΩcm)。

Some cord to a surface hardness low Corrugating roll also therefore create top cord to boundaries Ma Hang and depression and wear process.

一些楞面硬度低的瓦楞辊还会因此使楞顶楞面产生麻坑和凹陷，加剧了磨损进程。

Cyaniding Cyaniding, or liquid carbonitriding as it is sometimes called, is also a process that combines the absorption of carbon and nitrogen to obtain surface hardness in low-carbon steels that do not respond to ordinary heat treatment.

氰化 氰化，有时称为液体碳氮共渗，也是一种结合了吸收碳和氮来获得表面硬度的工艺，它主要用于不适合通常热处理的低碳钢。

Cyaniding, or liquid carbonitriding as it is sometimes called, is also a process that combines the absorption of carbon and nitrogen to obtain surface hardness in low-carbon steels that do not respond to ordinary heat treatment.

氰化氰化，或液体碳氮共渗，因为它有时被称为，也是一个过程，结合吸收碳和氮获得表面硬度低碳钢不回应普通热处理。

The results show that during laser cladding, SiC of different forms is decompounded partially; with the increasing of the SiC adding content, the quantity of un-melt SiC increases and hardness of cladding layers improves.

结果表明，随着加入量的增加，熔覆层中未熔SiC含量增加，熔覆层硬度也随之提高；对比加入颗粒状和纤维状SiC的熔覆层的显微硬度表明，同含量情况下纤维状SiC的强化效果更显著；造成熔覆层硬度显著提高的原因是未熔SiC，析出相FeSiC的弥散强化和熔入的Si，C元素引起的固溶强化作用。

The main reasons bring hardness remarkable improvement are disperse reinforcement of un melt SiC and propitiation FeSiC, and solution reinforcement of decompounded Si, C.

造成熔覆层硬度显著提高的原因是未熔 Si C，析出相 Fe Si C的弥散强化和熔入的 Si，C元素引起的固溶强化作用。

The motor bearings should be type M vacuum degassed for uniform hardness on bearing surface.

l 为了保证机组可靠运行，传动齿轮精度达到AGMA12级，设计寿命长达10万小时以上；主机采用真空去磁轴承，设计寿命在5万小时以上。
