Upon successful completion of this course, the student shall:

Outcomes	Assessments – How it is met & When it is met
List how engineering materials, metals, polymers, ceramics, and composites are related in origin and structural characteristics. (crystal structure, organic composition and properties, basic chemistry and atomic structure)*	This material is covered in Chapters 2 and 4, over physical properties and structures of metals. It is also covered in the last section over composite materials (non-metallic origin, including organic). Exams at Week 5, 10 and Final Exam
List the properties that must be reviewed when making materials selections. (modulus of elasticity, tensile strength, yield strength, shear strength)*	Physical properties of materials is covered in Chapter 7, Plastic Deformation, as well as during lab exercises performing yield, tensile and shear strength testing. Exams at Week 5, 10 and Final Exam Bi-weekly Lab Reports
Differentiate between the properties of stiffness, strength, and toughness. (stiffness – modulus, strength – tensile strength, yield, shear strength)*	Physical properties relating to stiffness, strength and toughness are covered during lab exercises using Charpy Impact testing, tensile and shear testing. It is also covered in Chapters 4 and 7, Structure of Metals and Plastic Deformation. Exams at Week 5, 10 and Final Exam Bi-weekly Lab Reports
Define vocabulary used in steel terminology.*	Multiple lessons contain vocabulary relating to steel. Chapters 11 thru 17 cover steel related terms from cast iron to stainless steel. This vocabulary is also presented during most labs. Exams at Week 5, 10 and Final Exam Bi-weekly Lab Reports
Describe how steels are made. (melting, casting, hot rolling, cold rolling)*	This material is covered within Chapter 11 thru 17, specifically Chapter 11 on the melting, casting and rolling. Exam at Week 5 and Final Exam
List and describe the common heat treatments used on steels. (annealing – heat and slow cool, quenching - fast cooling, tempering - low temperature reheating)*	Heat treating is covered in Chapters 13 and 14, Cooling Rates of Steel and Heat Treating. Lab exercises involved in quench and tempering high carbon steel is performed, as well as forging steel above its critical temperature. Exams at Week 5, 10 and Final Exam
Describe how cold working and alloy additions alter steel properties. (increase strength, lower ductility)*	This material is covered in Chapter 7, Plastic Deformation as well as in lab exercises where steel is cold worked and hardness is monitored. Exams at Week 5, 10 and Final Exam Bi-weekly Lab Reports
Specify tool steels based upon their properties and the heat treatment to which they have been subjected. (evaluate operating temperature, strength, stiffness, cyclic loading)*	Tool steel material is covered in Chapter 15, along with a presentation of tool steels, their make-up and properties. A presentation of carbide cutters is also given. Exams at Week 10 and Final Exam
Develop a guideline on how to screen candidate materials and arrive at the proper choice.*	Chapter 7, Plastic Deformation, along with tensile tests and non-destructive hardness testing lab exercises are used to develop skills in material selection. This is also covered in each chapter as non-ferrous and non-metallic material information is introduced. Exams at Week 5, 10 and Final Exam Bi-weekly Lab Reports
Demonstrate a basic understanding of polymers, aluminum, and copper	Chapters 18 through 23 cover non-ferrous materials, plus a presentation of composite materials provides information. Week 10 midterm and Final Exam
