CE 3.1 Project InformationName of the project: Synthesis and Characterization of Nickel Free Shape MemoryAlloyLocation of the project: [PLEASE FILL]Project Duration: [PLEASE FILL]Organization: [PLEASE FILL]Role and Designation during the time: [PLEASE FILL]CE 3.2 Project BackgroundCE 3.2.1 Characteristics of the projectShape memory alloys (SMA's) are the class of Smart Materials known for their fantasticmemory wonders went with down to earth relevance. The exceptional utilitarian properties ofSMAs are Shape Memory Effect (SME) and Super-elastic Effect (SE). Shape memory alloysmay have two various types of Shape Memory Effect; these are regular known as one-way shapememory impact (OWSME) and two-way shape memory impact (TWSME). The Shape MemoryEffect (SME) changes with temperature variety are for the most part ascribed to martensitic stagechange. Normally these alloys demonstrate two change stages: austenitic (parent stage B2 cubic)at high temperature and martensitic (B19'monoclinic stage) at low temperature. Ni– Ti alloys arethe most encouraging Shape Memory Alloys as far as viable materialness. Truth be told,notwithstanding austenite-marten site stage change, there is another middle stage known as the

'R-stage change' where, after bringing down the temperature, the austenite cubic structure canmutilate step by step to a rhombohedra cross section structure. Another essential part of NiTialloys are identified with the biocompatibility, unrivaled mechanical and consumption properties,which have permitted the more prominent utilize and work in biomedical field. Shape MemoryAlloys additionally give arrangement in a few fields, for different applications e.g., Actuator,Automotive area, Aircraft wings, Robots and bracing framework.CE 3.2.2 Objectives developed for the projectThe objective which I had followed during the research of this project topic are discussedbelow:To understand the different ways in which memory alloys are created To understand their working procedureTo synthesize different memory alloys for the advantage of understanding the researchprocedure. CE 3.2.3 My area of workFor this project research I had conducted research on the different memory alloys. For theextensive part of the project I had experimented with the production of the memory alloy. I haddeveloped two Cu-Al-Mn Shape Memory Alloy using two methods of production: MechanicalBall Milling and Induction Melting.
