讲座摘要
Automobiles are the second largest source of greenhouse gas emissions, a fact which has attracted stringent environmental regulations globally urging automotive manufacturers to reduce emissions. For instance, new policies have been launched by European Union in order to achieve its long-standing objective of limiting average CO2 emissions of automobiles to 95g/km by 2020. Such requirement on CO2 emission is one of the most important challenges facing automotive industry. One effective solution to reduce greenhouse gas emission is by reducing vehicles' weight, which can be achieved using lightweight materials. The most common lightweight materials for automobiles are Advanced High Strength Steels (AHSS), which include Dual phase (DP) steel, Transformation-induced plasticity (TRIP) steel, Twinning-induced plasticity (TWIP) steel and more recently Quenching and partitioning (Q&P) steel and medium-Mn TRIP steel. The high strength offered by AHSS leads to thinner components and therefore lighter automobiles can be made. The present talk will discuss the deformation mechanism of TWIP, Q&P and medium-Mn TRIP steels.
