The results show that the hardness of H13 steel after annealing depends on size, relative amount and type of carbide.
明确了H13钢退火后硬度的高低与碳化物粒子的大小、相对量及碳化物的类型的依赖关系。

The mechanical property of m is higher than that of annealing structure after warm compression, probably because of the fine ferrite grain with uniformly distributed nano-sized carbide particles.
温变形后组织的力学性能高于退火变形组织的原因是晶粒的细化和纳米碳化物的均匀分布。

The results show that the spheroidal annealing structure in which the size and spacing of carbide particles are bigger can he gained through suitably rising the spheroidal annealing temperature.
