This standard is issued under the fixed designation A; the number immediately Practice E—Copper–Copper Sulfate–Sulfuric Acid 1 These practices are under the jurisdiction of ASTM Committee A01 on Steel. In MTC of L material it is mentioned that IGC Test as per ASTM A practice E is carried out and the material is passed the test. Why L. In reading over ASTM A it seems that the intergranular corrosion susceptibility Personally, I would go for A Practice E in the as welded.

Intergranular corrosion shows up as the dark black lines around the grain boundaries. We provide accurate, repeatable results along with world-class customer service.

The first and fastest step is the ASTM A Practice A, a rapid same-day screening method in Oxalic acid to determine the susceptibility to intergranular corrosion. Classification of the structure after A Practice A analysis will determine if the material is acceptable or if additional testing is required.

If you are not sure, please contact us for assistance. Based on your materials, application, and requirements, the other 4 methods provide specific focuses.

In everyday applications, corrosion varies by materials and solutions. For example, in highly oxidizing solutions, intergranular attack can occur due to intermetallic phases, while attack of carbides may occur somewhat less oxidizing solutions.

Due to the variance of attack in different materials, numerous methods Practices B-F are used to assess intergranular corrosion. These tests are often run as a qualification test to ensure each batch of stainless steel is properly prepared.

Each ASTM A Practice specification includes a list of the grades of stainless steels and the acceptable etch structures for the specific alloys. For example, many low-carbon and stabilized stainless steels e.

The test is generally performed for acceptance of materials, but not sufficient for rejection of materials. The Minitab 15 software was used to determine the correlation by linear Regression methods. The value obtained was subjected to a recheck to check the percentage error.

The percentage error between the experimental and theoretical value was minimal. Fakkir Mohamed, B. Praveen Kumar, P.

Arvind Singh, V. Thenambika, J. Kirubanidhi, Manoj Gupta Abstract: Magnesium alloys with enhanced thermal stability are being developed for automobile engine applications. Development of new Mg-alloys is underway and Mg-Sn alloys are a promising option.

In Mg-Sn alloy, the Mg2Sn phase has high thermal stability and is expected to enhance the high temperature properties. In this study, Mg-5Sn alloy is incorporated with Ag as a minor alloying element 0. The creep behavior of the Mg-Sn-Ag alloy is investigated using the impression creep technique. The impression creep tests were carried out under punching stress in the range of MPa and temperature of K, for dwell times up to 5 hours.

The results highlight that creep of the alloy was load and temperature dependent, i. Megavarnan, G. Rajamurugan, R.

It is a joining process that fuses the base metal to make the weld. The results were analyzed by means of the mechanical properties such as tensile strength, bend test, microstructure and hardness was carried out for both along and across the grain flow direction of the weldments.


The important implication about grain flow is that some mechanical properties vary with respect to orientation of the grain flow.

The strength and hardness are primarily varied based on the grain flow direction.

The desirable properties associated with retarding crack propagation can see significant differences depending on the grain flow and the direction of the moving crack.

The optimum alignment occurs when the maximum principal stress perpendicular to a potential crack or fracture is aligned with the grain-flow lines.

On testing the mechanical properties, it reveals that along the grain flow direction has Nandhakumar, R. Vijayakumar, Senthil Padmavathy, N. Nagasundaram Abstract: Design of Experiments is employed to study the stimulus of cutting parameters such as feed rate, spindle speed, depth of cut in the turning operation of AISI and optimizing the value of those parameters for getting the higher material removal rate MRR and minimal surface roughness.

A prediction model has been developed by using the above influencing parameters. It is shown that feed rate is the main parameter in influencing the surface roughness, which is being followed by spindle speed and depth of cut.

It is found that surface roughness and feed rate were directly proportional to each other for some extent.

The confirmation tests were carried out to with the optimum set of parameters and are verified with test results. Ashish, Leo A.But there is a high difference between a qualitative hazard identification method and audit type method since HAZOP is mainly used in a process industry and an audit is mainly used for inspecting the safety management of the industry thus in the WHIPP they used guidewords same as HAZOP uses keywords to identify the hazards and risks associated with the hazards while they perform the walk down in the company and are assessed with a checklist.

Gerald, R. The corrosion rate during each boiling period is calculated from the decrease in the w eight of the specimens. Once the specimen has been subjected to the solution boil, it is bent through and over a diameter equal to the thickness of the specimen being bent. A hybrid MMC was developed for the cylinder liner of advanced diesel engines. An optimal parameter combination of the turning method is obtained by victimization of Grey Relational Analysis.
