Class Objectives
/Class Outline
This class consists of lectures on powder metallurgy and plastic working, which are important sectors of production and processing technology. Students can understand processing principle of powder metallurgy and plastic working, important technical issues (perspective for designing good working process), selection of processing method and its improvement through this class. Class objectives are as follows:
1) To acquire the ability to understand and describe the types of plastic working (material production, bulk forming, sheet metal forming and so on) and their features. (B)
2) To acquire the ability to estimate forming load and forming limit in plastic working. (B)
3) To acquire the ability to understand and explain the role and the principle of numerical simulation in metal forming process. (B)
4) To acquire the ability to understand and explain the principles and features of the powder metallurgy processing method. (B)
5) To acquire judgment on introducing sintered parts (powder metallurgy products) into designs of mass-produced equipments. (B) 
Class Schedule lesson1 -- Types of plastic working (metal forming), point of view to design good working process, fundamentals of theory of plasticity (part 1).
lesson2 -- Fundamentals of theory of plasticity (part 2), plane strain compression, rolling.
lesson3 -- Extrusion, drawing, forging and working force of these processes.
lesson4 -- Mechanism of ductile fracture and its criterion.
lesson5 -- Sheet metal forming: forming limit in deep drawing and stretch forming, springback.
lesson6 -- Influences of temperature and forming speed on workability.
lesson7 -- Thermomechanical treatment, controlled rolling, effect of friction on plastic working, questions of report.
lesson8 -- Numerical simulation and process-design optimization in metal forming.
lesson9 -- Introduction of new production technology of sintering-material by powder metallurgy processing method.
lesson10 -- Position occupied in the production and processing outline of powder metallurgy processing method, raw materials: general properties of the powder.
lesson11 -- Molding: transmission of force, lubrication and the movement of the powder in the mold, dimensional accuracy.
lesson12 -- Sintering: enhanced binding of the powder particles and the motion of atoms, dimensional changes associated with sintering and change in the shape of the pores originating from the voids between the powder particles.
lesson13 -- Features:The material of the sintering machine material, questions of report.
lesson14 -- Development of future expected.
lesson15 -- Spark sintering utilizing electric energy and its sintering mechanism and characteristics of their compacts.

Preparation and
Review
Plastic working (Hino)
Lesson 1 -- lesson 8: Review of keywords in the class and perusal of the reference book.
Powder metallurgy (Matsugi)
Lesson 9 --lesson 15: Perusal of handouts and review of keywords in the class. 
Requirements It is desirable that students have already learned Materials Science, Mechanical Material I and II, Theory of Plasticity, and Fusion and Solidification Processings I. 
Grading Method Grading is determined by achievement of the "Class Objectives" and learning attitude. The achievement of the "Class Objectives" (80% of grading) is assessed by the written final examination, and the learning attitude (20% of grading) is evaluated by two reports. More than 60% of total grading is necessary for passing.
