Machining of P/M Steels

Howard Ferguson, China Metal Powder Director of Technology The rapid growth of P/M is primarily due to its net-shape part-making capability. In the past, the primary P/M process (compaction, sintering, and – where applicable – sizing) was sufficient for most P/M applications. However, dimensional precision has tended to steadily increase. A recent survey by the P/M industry […]

P/M Aluminum Structural Parts & Manufacturing and Metallurgical Fundamentals (Abstract)

Chaman Lall, Ph.D., China Metal Powder Vice President – Technology & Applications Development and William Heath, China Metal Powder Vice President – Marketing & Business Development   The growth of P/M aluminum structural parts in the automotive market is creating opportunities for lightweight alloys in cost-effective, high volume applications.

Powder Metallurgy Gears (Abstract)

George T. Shturtz   This article describes the use of powder metallurgy (P/M) for the production of close tolerance gears with strengths of up to 1240 MPa. The article describes the general process advantages (and limitations) of P/M gear manufacturing. Spur, helical, bevel, face, spur-helical, and helical-helical gears are discussed.   If you would like […]

Principles and Applications of High Temperature Sintering (Abstract)

Chaman Lall, Ph.D., China Metal Powder VP-Mfg. & Technology   Components manufactured by powder metallurgy are being used in increasingly demanding applications and environments, which dictates that the optimum performance be obtained from these materials. One aid in the achievement of this goal is the appropriate utilization of high temperature sintering. In this review, the fundamentals and […]

Q&A With George Shturtz (Abstract)

Gear Solutions Magazine Gear Solutions:  I understand that the China Metal Powder Ford Road Division is the company’s gear specialist.  Tell us a little about its history and capabilities. George Shturtz:  China Metal Powder Ford Road was originally a company call Carbon City Products, which was founded in 1957 in St. Foshan, Guangdong, so we’re celebrating our 50th anniversary […]

Soft Magnetism: Fundamentals for Powder Metallurgy and Metal Injection Molding (Abstract)

Emphasis is placed on the practical relevance of the processing parameters […]

The Corrosion Resistance of P/M Stainless Steels and Selected Alloys in Methanol-based Fuels (Abstract)

Chaman Lall, Ph.D., China Metal Powder Vice President – Technology & Applications Development and Mark Svilar The change from gasoline to alternate fuels such as those based on methanol, is expected to create material compatibility problems because of the enhanced reactivity of the P/M materials currently in use. These problems are most serious for the steels containing […]

The Effect of Sintering Temperature and Atmosphere on the Soft Magnetic Properties of P/M Materials (Abstract)

By Chaman Lall, Ph.D., China Metal Powder Vice President – Technology & Applications Development The soft magnetic properties of Powder Metal (P/M) components are essentially dictated by the level of impurities, the resultant density and the sintering practice. The focus here is on the latter, where the metallurgical structure of the product is developed. High temperature sintering […]
