Description: Scanning Probe Microscopy (SPM) is a powerful set of techniques used to image and manipulate surfaces at the nanoscale by scanning a probe over a sample’s surface. It provides high-resolution images and allows the characterization of surface properties with exceptional detail. There are several types of SPM, including Atomic Force Microscopy (AFM), Scanning Tunneling …
Description: Nuclear Reaction Analysis (NRA) is an analytical technique used to determine the elemental composition and depth profiling of materials. It involves the use of nuclear reactions induced by high-energy (MeV) charged particles (such as protons or deuterons) to probe the elemental composition of a sample. Principle: NRA relies on the interaction of high-energy particles …
Description: Particle-Induced X-ray Emission (PIXE) analysis is a technique used for elemental analysis and characterization of materials. It involves bombarding a sample with a beam of high-energy (MeV) charged particles (usually protons or alpha particles), which leads to the emission of characteristic X-rays from the atoms in the sample. These emitted X-rays are then detected …
ASTM A309 – Standard Test Method for Weight and Composition of Coating on Terne Sheet by the Triple-Spot Test (Withdrawn 2015) Description: Significance and Use 3.1 A coating of terne metal on iron or steel articles is intended to provide drawability, solderability, or corrosion resistance, or combination thereof, which can require different amounts of coating. Specifications …
ASTM A275 – Standard Practice for Magnetic Particle Examination of Steel Forgings Description: Significance and Use 4.1 For ferromagnetic materials, magnetic particle examination is widely specified for the detection of surface and near surface discontinuities such as cracks, laps, seams, and linearly oriented nonmetallic inclusions. Such examinations are included as mandatory requirements in some forging standards …
ASTM A262 – Standard Practices for Detecting Susceptibility to Intergranular Attack in Austenitic Stainless Steels Description: Significance and Use 6.1 Use of the etch test allows rapid acceptance of specific lots of material without the need to perform time-consuming and costly hot acid immersion tests on those lots. Abstract This specification covers the standard practices for …
ASTM A255 – Standard Test Methods for Determining Hardenability of Steel Description: Significance and Use 3.1 This test method covers the procedure for determining the hardenability of steel by the end-quench or Jominy test. The test consists of water quenching one end of a cylindrical test specimen 1.0 in. in diameter and measuring the hardening response …
ASTM A254 – Standard Specification for Copper-Brazed Steel Tubing Description: Abstract This specification covers double-wall, copper brazed steel tubing suitable for general engineering uses, particularly in the automotive, refrigeration, and stove industries for fuel lines, brake lines, oil lines, heating and cooling units, and the like. The tubing shall be made by rolling steel strip …
ASTM A247 – Standard Test Method for Evaluating the Microstructure of Graphite in Iron Castings Description: Significance and Use 4.1 The comparison of observed graphite particles with the structures shown in the charts give only purely descriptive information on the type, distribution, and size of the graphite in the sample being evaluated. It does not indicate, …
ASTM A194 – Standard Specification for Carbon Steel, Alloy Steel, and Stainless Steel Nuts for Bolts for High Pressure or High Temperature Service, or Both Description: Abstract This specification covers a variety of carbon, alloy, and martensitic and austenitic stainless steel nuts. These nuts are intended for high-pressure or high-temperature service, or both. Bars from …
