The study of damage of low temperature brittleness on high manganese steel has been carried out by theoretical analysis and a series of impact tests.
通过理论分析和系列冲击试验，对高锰钢出现的低温脆性损坏进行了分析研究。
The results showed that the low temperature brittleness and impact strength of PP were improved observably by blend with FU.
结果表明，FU的加入可明显改善PP低温脆性，提高冲击强度。
