课程名称：制造与材料科学 课程概述：本课程以全面而简洁的方式介绍材料科学/工程材料，包含40多个讲座，时长仅约3小时！非常适合将材料科学或工程材料作为学科之一的工程学学生。课程涵盖的主题包括： 1. 原子与晶体结构 - 晶体系统、布拉维晶格、米勒指数、晶胞特征、体心立方（BCC）、面心立方（FCC）及六方密堆积（HCP）结构。 2. 晶体缺陷 - 点缺陷（元素与化合物晶体）、线缺陷、面缺陷和体缺陷。 3. 颗粒理论 - 颗粒形成、颗粒大小测量、颗粒结构、变形类型及机制。 4. 多相结构 - 固体溶液、相图（单组分和双组分）、共晶微观结构、各种不变反应类型、Fe-C相图及TTT图。 5. 钢的热处理（HTS） - 硬化、回火、奥氏体化、马氏体化、退火、应力消除、球化和正火、渗碳。 6. 材料的机械性能 - 拉伸强度、冲击强度、疲劳强度、蠕变及硬度测试（布氏、维氏和洛克韦尔）。 7. 工程金属 - 普通碳钢、合金钢、铸铁、非铁金属。 最适合的对象：机械与土木工程本科生和研究生，准备学术或工程类（竞争性）考试的学生，学有材料科学作为一门学科的大学生。 注意：请观看课程的预览（免费讲座），以了解我的口音是否适合您。本课程录制时间稍早，可能会影响某些学生理解我讲课的口音。但应许多好奇学生的要求，我在课程中添加了非常清晰的字幕，以便您在无法理解我口音时可以通过字幕进行辅导。
The course consists a comprehensive yet concise approach towards Material science/Engineering materials. Spanning around 40+ lectures yet completing in just around 3 Hours!!. Perfect for engineering students having one of their subject (out of the dozens others) as material science or engineering materials. Covered topics are listed below.Atomic & crystal structures - Crystal systems, Bravais lattices, Miller indices, cell characteristics, BCC (Body centered cubic), FCC (Face centered cubic) and HCP (Hexagonal close packing) structures.Crystal Imperfections - Point (both elemental and compound crystal's), Linear, Planar, and bulk defects.The grain theory - Grain formation, measurement of grain size, grain structure, deformation types and mechanism.Multiphase structure - Solid solution, phase diagram (Unary and Binary), eutectic microstructure, types of invariant reactions, Fe-C phase, TTT diagram.Heat treatment of steel (HTS) - Hardening, tempering, austempering, martempering, annealing, stress relieving, spheroidizing, normalizing, case hardening.Mechanical properties of material - Tensile strength, Impact strength, Fatigue strength, Creep and hardness testing (Brinell, Vicker's and Rockwell).Engineering metals - Plain carbon steel, alloy steel, cast iron, non-ferrous materials. Most suitable for - Mechanical and civil engineering undergraduates and graduates,Students preparing for academic or competitive (engineering)examinations,University students having Material science as one of their subjects.PS - Please see the PREVIEW (FREE) lectures to know your adaptability with my accent.This course was recorded a while ago & my accent might trouble some students. However I have overcame my accent problems in my latest courses.However on demand of many curious students, I have added very clear CAPTIONS (Subtitles) in the course so that you can read it from there if you can't understand my accent.
