HEAT TREATING SOCIETY NEWS

A special riverboat cruise on the Savannah River featur-

ing a delicious dinner and perfect weather was a highlight of

the conference. This IFHTSE Congress providedmany oppor-

tunities for fellowship and networking. It was well organized

and attendees from all over the globe enjoyed themselves.

Special thanks goes to the domestic and international orga-

nizing committees, ASM staff including Jeanelle Harden and

Lindy Good, and sponsors Houghton International Inc. and

Linde Gas for a successful conference.

REGISTRATION NOW OPEN

FOR HEAT TREAT MEXICO

The ASM Heat Treating Society will present a new

global event,

Heat Treat Mexico: Advanced Thermal Pro-

cessing Technology Conference and Expo,

scheduled

for September 20-23 at the Fiesta Americana in Queretaro.

The conference is designed for maintenance supervisors,

metallurgists, and production engineers and will provide a

bridge for relevant new technology for thermal processing

and how it is applied to the production environment in Mex-

ico. In addition to comprehensive technical programming,

exhibitors will have the opportunity, in a classroom environ-

ment, to present the implementation of their technologies

and products applicable to heat treating. Each presentation

will be reviewed for technical merit and will include minimal

sales-oriented content. For more information or to register,

visit

asminternational.org/web/htmexico.

CALL FOR PAPERS NOW OPEN

FOR HEAT TREAT 2017

Heat Treat 2017, the biennial co-located show from

the ASM Heat Treating Society and the American Gear

Manufacturers Association, is now seeking papers. Confer-

ence organizers are looking for original, previously unpub-

lished, noncommercial papers for both oral and poster

presentations. Technical areas of interest include additive

manufacturing, advanced processes, advances in heat

treating, applied energy, atmosphere technology, auto-

motive lightweighting, cryogenic treatment, induction

heat treating, microstructure development, non-ferrous

alloys, quenching and cooling, surface engineering, ther-

mal mechanical processing, vacuum processes and tech-

nology, and more.

Submit your abstract by December 30

to be considered for the Heat Treat 2017 technical pro-

gram.

RESEARCH PROGRESS: NONDESTRUCTIVE

MEASUREMENT TECHNIQUES

The Center for Heat Treating Excellence (CHTE) at

Worcester Polytechnic Institute (WPI) in Massachusetts has

spent the past three years working on a research project

aimed at measuring surface hardness and case depth on

carburized steels for process verification and control. CHTE

is an alliance between the industrial sector and university

researchers that addresses heat treating needs. The expecta-

tion is that project results will enable companies to improve

the quality of heat treated products faster and more cost

effectively.

According to lead researcher Richard Sisson, Jr., George

F. Fuller Professor of Mechanical Engineering at WPI, and

CHTE technical director, the heat treating industry needs

accurate, rapid, and nondestructive techniques to mea-

sure surface hardness and case depth on carburized steels

for process verification and control. “Current measurement

methods require destructive testing with traveler specimens

that cannot always represent the configurations of the pro-

ductionpart, nor theassociatedsubtletiesof thermal history,

carbon atmosphere, and geometry influenced diffusion. Our

research will eliminate much of the guesswork,” says Sisson.

Another challengewith the traveler specimenmeasure-

ment method is that it often requires periodic production

part cut-ups to validate the hardness and case depth of parts

after carburization, especially for critical shaft and gear teeth

configurations. A key issue for researchers is to distinguish

between hardness and residual stress, as most techniques

currently used to measure case depth are not only sensitive

to hardness distribution, but also residual stress.

at measuring surface hardness and case depth on carburized

steels.
