Welcome to join the English training program!;Specialized English for Materials Forming Control Engineering;My action plan for the training course: Each lecture will be divided into two parts: Step one: I will introduce some new words related to the topic to be discussed. Then, the fundamentals of the topic will be presented. Step two: the passage in the training material will be discussed among the participants. For the given issue (or raised by the trainees), discussions among the trainees will be carried out. If possible, some listening comprehension will be given before each class.;★Shotgun quiz★;Mechanical Manufacturing and Materials Forming机械制造基础与材料成形;Crystallization of Pure Metal 纯金属的结晶 crystallization n. 结晶 nucleation n. 形核 growth n.

Human beings must know the structures of metal materials and how to make and process different metal materials.;;What is MSE?;;Course Objective... Introduce fundamental concepts of Material Science Engineering You will learn about: ? material structure ? how structure dictates properties ? how processing can change structure This course will help you to: ? use materials properly ? realize new design opportunities with materials ? understand material properties;Q1: What is materials’ composition? ? Composition: the chemical make up of a material! ? Examples: C – carbon; Si- silicon; Mn-manganese; S-sulfur; P-phosphorus. Q2: What are materials’ properties? ? Mechanical Properties describe how well a material withstands applied forces, including tensile or compressive, impact, cycling or
