Nickel and Nickel Alloys

ASM HOMESTUDY COURSE (15-Lesson Series)

Course Overview:

• Provides a general overview of nickel alloys and their usage
• Shows where nickel and its alloys are used and how they differ from other material systems
• Fills a void left by materials engineering programs that emphasize only ferrous materials

Where long performance life and reduced lifecycle costs are at issue, nickel and nickel alloys can frequently provide an excellent alternative. Today, as long mill lead times attest, higher alloyed materials are being used to an even greater extent. To provide dependable information on when to use these alloys--and in which applications--this course has been developed.

By providing a basic understanding of nickel alloys, and citing examples of applications in a number of diverse industrial segments, this course will help attendees more effectively select the right alloy group for specific applications.

This course was developed to compensate for the general lack of knowledge in the market place regarding nickel and nickel alloys. Because of universities' focal points of ferrous materials, metallurgical and materials engineering students usually graduate with little knowledge of nickel alloys and their usage.

What You'll Learn:

• When to consider nickel alloys, including physical, mechanical and environmental conditions that dictate their use
• How nickel alloys differ in structure from the martensitic and ferritic materials
• How nickel alloys are very corrosion resistant, how they react in various environments and how their alloying constituents affect corrosion resistance
• Major applications in key industries

Course Outline:

1. Introduction to Nickel: history of nickel; its natural occurrence; early usage; processing; consumption and demand.

2. Properties of Pure Nickel: general characteristics of pure nickel and various alloys with respect to physical properties.

3. Solid Solution Nickel Alloys: alloy groupings and composition; effect of alloying elements.

4. Precipitation Hardening Nickel Alloys: alloy definition and composition; precipitation hardening mechanisms.

5. Melting/Casting: comparison of available melting and casting techniques.

6. Mechanical Properties: provides a basic understanding for basic alloy groups, including effect of alloying elements and forming process.

7. Hot Forming: forging; hot rolling; extrusion.

8. Cold Forming: explores typical cold working processes and resultant microstructure.

9. Heat Treating: examines various heat treatments used to enhance mechanical properties; reduce stress; improve microstructure.

10. Machining: unique aspects of machining nickel alloys; recommended parameters for machining trials.

11. Welding: basic welding processes and techniques, with guidelines for joint design; heat treating; recommended filler metals.

12. Corrosion Principles: how basic principles relate to use of nickel alloys; effects of various alloying elements on corrosion mechanisms.

13. Aqueous Corrosion: analyses corrosion in basic aqueous environments; reviews various nickel alloy groups for effectiveness.

14. High Temperature Corrosion: defines and characterises hi-temp corrosion mechanisms and reviews various nickel alloy groups for effectiveness.

15. Applications: basic applications and a tutorial in alloy selection.

Who Should Enrol:

This course has been developed for design, metallurgical and maintenance engineers; materials specifiers; fabricators; and heat treaters. Sales staff form industry or metal distribution and purchasing staff also will benefit. Taking this course requires a basic understanding of metallic materials. A formal degree is not required, but participants should understand terms used in defining metals
