• Ultra-high Strength Steel heat process mechanical property energy spectrometer Abstract: Microstructure and mechanical property variation vs. heat process was investigated by means of metallography and electron microscopy in Ultra-high Strength Steel with tensile strength 1000Mpa. The results show that microstructure variation in the steel with tempering temperature increasing is as follows:tempered martensite→main tempered sorbite and a small amount of M/A, at the meantime, growing in quantities and volume of second-phase, always decreasing in strength, firstly increasing and then decreasing in impact energy and elongation. Study on precipitated mechanism of second-phases, the crystal structure and volume of precipitation was characterized by TEM observation and energy spectrometer.
