2003 TMS Annual Meeting & Exhibition: Short Courses—Heat Treatment of Wrought and Cast Aluminum Alloys

March 2–6 · 2003 TMS ANNUAL MEETING · San Diego, California
 

ABOUT THE PRESENTERS

Murat TiryakiogluDr. Murat Tiryakioglu received his Bachelor of Science Degree from Bogazici University, his M.Sc. and Ph.D. in Engineering Management degrees from the University of Missouri-Rolla, and his Ph.D. In Metallurgy and Materials Science degree from the University of Birmingham, UK. He worked at Tiryakioglu Metals Co., Inc, and The Boeing Co. on aluminum castings and heat treatment. He is the founder of Advanced Manufacturing Institute at Western Kentucky University, where he conducted research on heat treatment of aluminum alloys. Dr. Tiryakioglu is currently an Associate Professor of Engineering at Robert Morris University, and has served as a consultant to companies including Sumitomo, Tyco and Alcoa.

James StaleyDr. James T. Staley, Sr. recently retired after 35 years at Alcoa in R&D and operations. There he developed extensive experience in developing and applying heat treatments for aluminum alloy products. He led teams which wrote the Chapters on Metallurgy of heat treatment and general principles of precipitation hardening in Aluminum: Properties and Physical Metallurgy and Heat Treatment of Aluminum in an ASM International Metals Handbook. He continues to teach the metallurgy of heat treatment to Alcoa employees. He was awarded the James Douglas Gold Medal for distinguished achievement in nonferrous metallurgy by AIME and is a Fellow of ASM International.

Who Should Attend:
This 2-day course is intended for metallurgists, engineers, and technicians employed in either research or operations at facilities where cast or wrought aluminum alloy products are heat treated. Operations both at producers and users will be covered.

Course Overview:
The course combines theory with many practical examples. Strengthening mechanisms in aluminum alloy products are first reviewed. Then the general principles of precipitation hardening including phase diagrams are discussed. This is followed by an overview of the metallurgy of heat treatment. The hardening precipitates in the major alloys will be identified. A major element of the course is a description of how to use simple kinetic equations to predict effects of quenching and aging on properties. Graphical computer programs that illustrate these points will be demonstrated.

Contents of the course include solution heat treatment of castings with emphasis on homogenization and rounding of Si particles and effects of time and temperature. Discussion of the important step of quenching will include quench sensitivity; water quenching and geometry; and effects of quench on residual stress, distortion, corrosion, strength, and fracture toughness. Examples will be taken from 3XX, 2XXX, 7XXX, and 6XXX alloys. A method of predicting the properties using a Time-Temperature-Property C-Curve and a cooling curve will be described, and the difference between T-T-P and C-C-P (Continuous Cooling Property) Curves will be explained. Interactions between quenching and aging will also be covered. Examples of natural aging and effects of time and temperature of artificial aging will then be discussed. Examples of the contrasting effects of cold work prior to aging 2XXX and 7XXX alloy products will be shown and reasons for the behaviors discussed. Multi-step aging treatments will also be discussed with emphasis on T7 aging of 7XXX alloy products and low-high temperature aging of Al-Si castings.
