求翻译：热处理后，合金的硬度都比铸态低冲击韧性都比铸态高，说明热处理后组织均匀化使硬度降低冲击韧性升高。是什么意思？

After heat treatment, the alloy hardness than the cast state of low-impact toughness than cast high, indicating the uniform and the hardness to reduce the impact toughness increased after heat treatment.

Heat-treated, alloy casting the hardness is greater than normal low-impact toughness than cast-on, high-heat evenly organized after the hardness increases impact toughness.

After the heat treatment, alloy degree of hardness is all lower than the cast condition the resilience to be all higher than the cast condition, after showed the heat treatment organizes the uniformization to cause degree of hardness to reduce the resilience ascension.

After heat treatment, hardness of the alloy is lower than that of cast high impact toughness than cast, indicate tissue homogenization reduce hardness after heat treatment impact toughness to rise.
