Grain size and its influence on materials properties.(THE HEAT TREAT DOCTOR)

From: Industrial Heating | Date: August 1, 2005| Author: Herring, Daniel H. | Copyright information

As metallurgists, we know the importance of grain size, and as heat treaters, we need to be sure we understand how grain size will affect mechanical properties especially when designing our process recipes. Let's learn more.

Grain size specifics

The grain size of carbon and alloy steels is generally understood to mean prior austenitic grain size. On heating steel through its critical range, transformation to austenite takes place. The austenite grains are ext...

Direct measurements of grain size in low-carbon steels using the laser ultrasonic technique
Metallurgical and Materials Transactions ; The laser ultrasonic technique has been used to determine grain sizes in commercial low-carbon steels. With an analysis method that employs scattering theory, absolute values of the grain size have been calculated directly from the ultrasonic traces without the need of any free-parameter fits or
Using Grain Size Analysis as the Basis for a Research Project in an Undergraduate Sedimentology Course
Journal of Geoscience Education ; ABSTRACT Multi-week, research style projects within the context of a one-semester undergraduate course provide scope to explore topics in depth and build student skills. I developed a research-style project for an undergraduate sedimentology course using grain size analysis of sediments that
Determination of Spatial Grain Size with the Area-Weighted Grain Area Distribution of the Planar Sections in Polycrystalline Materials
Metallurgical and Materials Transactions ; The electron backscattering diffraction (EBSD) technique has made it quite easy to obtain the grain area distribution in a planar section of the polycrystalline materials. Usually, area-weighted grain area and number-weighted grain area show completely different distribution profiles. Instead of
Smaller grain size leads to better materials.(NANOTECHNOLOGY)
Advanced Ceramics Report ; A scientist at North Carolina State University (NCSU), USA, has discovered that certain metals and ceramics can be produced with nearly zero structural imperfections when their grain structure is smaller than a certain critical size, typically a few to several nanometres. Not only would these
Target solves step coverage issues.
Semiconductor International ; Metals and alloys have been used for sputtering target materials in microelectronic applications including contacts, vias, interconnections, barrier layers for copper diffusion, and copper seed layers for copper electroplating.
