Effects of finishing rolling temperatures and reduction on the mechanical properties of hot rolled multiphase steel were investigated. Thermo-mechanical control processing (TMCP) was conducted by using a laboratory hot rolling mill, in which three different kinds of finishing rolling temperatures and reduction and various austempering times were applied. The results showed that polygonal ferrite, granular bainite and larger amount of stabilized retained austenite can be obtained by controlled rolling processes, and that the strain-induced transformation to martensite from the retained austenite can occur gradually when the steel is deformed during tensile test. Mechanical properties increase with decreasing finishing rolling temperature and increasing amount of deformation. The most TRIP (transformation induced plasticity) effect, and ultimate tensile strength (UTS), total elongation (TEL) and the product of ultimate tensile strength and total elongation (UTS×TEL) are obtained at 20 min. 相似文献

This study utilized a large sample of two-parent families from low-income rural communities to examine the contributions of father education and vocabulary, during picture book interactions with their infants at 6 months of age, to children's subsequent communication development at 15 months and expressive language development at 36 months. After controlling for family demographics, child characteristics, as well as mother education and vocabulary, father education and father vocabulary during the picture-book task were related to more advanced language development at both 15 and 36 months of age. Only mother education, but not vocabulary during book-reading was related to children's later language. These findings support the growing evidence on the importance of fathers in understanding children's early communication and language development. 相似文献
