Composition for preventing polyvinyl (PTA) stress corrosion cracking of 300 series stainless steel and its useA method, system and method for treating a stainless steel Bessel to prevent polythionic acid stress corrosion cracking are described. The composition contains premixed K2CO3 solution and can...
The 316 family is a group of austenitic stainless steels with superior corrosion resistance to 304 stainless steel. This alloy is suitable for welding because it has a carbon content lower than 301 to 303 series alloys to avoid carbide precipitation in welding applications. The addition of ...
Stainless steel does not easily corrode, rust, or stain with water as ordinary steel does. The origins of stainless steel date back to the early 1900s, when scientists noticed that chromium had a greater attraction to oxygen than iron did, so they added the element to steel.Studies prove th...
Beams of ions can be used to cut or “mill” narrow regions of materials to great accuracy. Surface modification. Plasmas can be used to modify the properties of materials by interacting on the surface of those materials in several ways. For example, tool steel can be hardened considerably ...
The present work investigated the composition evolution of the TMS series of Ni-base single crystal (SC) superalloys in light of the cluster formula approach systematically. The cluster formula of SC superalloys could be expressed with $${[}\overline{{{\
Stainless steel, custom-made connectors were added to both ends of the tube. Only when the furnaced reached the selected temperature, the alumina tube was then inserted in the tubular furnace. A constant flow of approximately 340 ml/min of 99.9% pure nitrogen (for the dynamic pyrolysis) or ...
A laboratory-scale SC fluid extraction system was used, and the extraction was performed as follows: 180 g of root powder sample was loaded into the stainless steel extraction vessel (volume: 500 mL). A thin layer of cotton was placed at the bottom of the extraction vessel prior to loading...
(2019). Briefly, the roots of intact plants were carefully washed to remove any remaining soil, during which time the roots were left as undamaged as possible, and dead roots were removed with stainless steel tweezers. One hole of rice plants was then transferred to 100 mL soil solutions ...
Eastern gray whales’ distribution range and plasticity in feeding behavior complicates the understanding of critical life-history such as pregnancy and lactation. Our goal was to determine if females who experienced gestation, gave birth, and lactated t
