When I was a student at university, a major theme is the progressive development of materials having ever greater strength and heat resistance, primarily to meet performance objectives. Unfortunately, the characteristics of such materials present challenges to the principal shaping …

Cast iron is normally not permitted for pressure containment components in hydrocarbon processing streams because of its brittleness, especially in areas where it could be quenched during the course of fighting a fire. However, cast irons are routinely used in …

The Geologic Time Scale (GTS) is a comprehensive framework that organizes Earth’s history into distinct intervals based on geological and biological events. It serves as a chronological timeline, enabling scientists to understand the age of rocks, fossils, and the evolution …

PMI (Positive Material Identification) verified that alloy materials are of acceptable chemical composition independent of any certificate and marking that may exist. API RP 578 is an excellent document for instituting an effective PMI program. MSS SP-137 is also another …

هر هفته، یکی از کتابهایی که خوانده‌ام را در اینجا معرفی می‌کنم و امیدوارم که چون خودم آن را با علاقه و لذت خوانده‌ام، خواندنش برای شما نیز دلنشین باشد و شاید کمک کند تا سررشته‌هایی برای مطالعه‌‌ی بیشتر پیدا …

The distribution of the alloying elements in an alloy steel depends on its composition. Many complex interactions can occur and, as the number and amount of alloying elements are increased, the complexity of the interactions also increases. However, there are …

The ASME Boiler and Pressure Vessel Code (B&PVC), is written to provide rules for the design, fabrication and inspection of boilers and pressure vessels. The first Boiler and Pressure Vessel Code (1914 Edition) was published in 1915; it consisted of …

مهندس باسابقه‌‌ای در جلسه‌ی آنلاینی که به زبان انگلیسی بود، متنها را از روی اسلایدها می‌خواند و می‌گذشت تا این‌که به اسلایدی رسید که فقط یک فرمول ساده داشت شامل یک خط کسری و یک رادیکال. کمی مکث کرد… کمی این‌پا …

These resources present topics on the materials selection which will give a better understanding on the selection methods and then find suitable materials for the applications. Some of them provide information and insight that can be employed in any discipline …
