Characterization of Internal Defects in Open Die Forgings

The defect is approximately 1.2 mm in length, with an additional 0.1 mm secondary section trailing below the primary section. There are definite layered defect sections, with voids intermittent throughout. The walls of the defect appear rough and irregular, with rupture type of topography.

What is Electrochemical Grinding and How it Works

What is Electrochemical Grinding? It is a process which is quite similar to the electrochemical machining. As per the name it is the metal removal process which is nothing but the combination of the grinding process and electrochemical process. It is also termed as the "electrolytic grinding" and "anodic machining".

Defects in Hard Chromium Deposits Part I Causes and Cures

The causes of and remedies for defects in hard chromium deposits are explored in the first of this two-part PSF article from 1984. Photomicrographs and SEM (scanning electron microscope) photographs will illustrate that most defects in various hard chromium deposits arise from defects in the basis metal. These defects may be in the original metal surface or may be caused by preplate finishing.

Processing can also affect the shelf life of almonds. In general, cutting (dicing, slivering, slicing, grinding) and blanching increases the exposed surface area and begins the oxidative process, which can reduce shelf life. Because both oil and dry roasting subject almonds to higher temperatures, roasted products must be protected from oxygen.

Quality prediction in continuous casting of stainless

Surface defects form during the continuous casting process. As a consequence of these defects, an intermediate grinding stage between casting and hot-rolling is needed to remove these defects. This causes large delays before slabs can be rolled, implying reduced throughput. These delays also mean that energy costs are increased because grinding

Metal Casting Process Manufacturing Process

A mold is formed into the geometric shape of a desired part. Molten metal is then poured into the mold, the mold holds this material in shape as it solidifies. A metal casting is created. Although this seems rather simple, the manufacturing process of metal casting is both a science and an art. Let's begin our study of metal casting with the mold.
