Effect of Al Content in Low Carbon High Manganese TWIP Steel Nisith Kumar Tewary1, a *, Swarup Kumar Ghosh1, b, Subrata Chatterjee1, c 1 Department of Metallurgy & Materials Engineering, Indian Institute of Engineering Science and Technology, Shibpur, Howrah – 711103, India atewarynisith@yahoo.com, bskghosh@metal.iiests.ac.in, cschatterjee46@yahoo.com Keywords: TWIP, Stacking fault energy, microstructure, mechanical property.
For the development of cost-effective and light-weight parts with improved safety and optimized environmental performance for automotive as well as structural applications, high manganese twinning induced plasticity (TWIP) steels is a preferential material [2].
The volume fraction of twin increases with strain and there is a rapid decrease of the mean free path of dislocations which results high levels of strain hardening in the material.
Therefore, the presence of Fe3Al compound in ferrite phase makes it brittle and lowers the ductility of the material.

According to all constraints, in a given material and structural type and loading condition the mathematical model of structural optimization is proposed, and then the model are solved with optimization principle and method.
Designer who passively check the program in previous can actively select design scheme by optimal design, as a result, the plan meeting the requirements of economic and security would be obtained where the material distribution is the most reasonable state.
The 3-D finite element analysis have been completed by ANSYS software, in which beams and columns are simulated by three nodes Timoshenko space beam element, shear wall and floor are simulated by eight nodes curved shell element, sections of SRC member are defined by user, Two-dimensional eight-node elements are used to simulate different materials section that obey the plane section assumption, the finite element model is shown in Fig. 2.
