heat treating manual (fourth edition) is the comprehensive resource that helps practitioners bridge the gap between research and practice in the science and technology of producing desired material characteristics with heat treatment.
as the leading heat treating manual in the industry, this book continues to bring all substantial advances in the field together into a single authoritative resource. updated with life testing and accelerated testing methods, new thermal processing equipment, newly discovered processes and theories, more versatile coating and doping methods, and more, this practical guide offers great immediate benefit and in-depth perspectives that become more valuable as experience and understanding increase.
the unifying theme of the heat treating manual is the exhaustive study and assessment of characteristics of commercial alloy steels and their heat treatment, based on a foundation of fundamentals in metallurgy, physics, thermal sciences, and mathematics. practical consideration of attack prevention, electrostatic surface charging, gravity action, and other forces that dictate economic operation and equipment selection affect ultimate process choices and performance.
the manual covers such topics as:
• tutorial on metallurgy and on-site hot-treating methods
• detailed coverage of forging, welding and forging impairments
• different types of furnaces, and the selection criteria for furnace requirements
• steps used to determine the proper heating and cooling procedures
• issues related to ferrous and non-ferrous alloy characteristics
• heat treating response criteria and hardening susceptibilities
• chemical, nitriding, and pvd coating processes
• quality control and quality assurance practices
whether used as an academic reference or a plant manual, the heat treating manual fourth edition offers extensive information to help readers with the science and technology of meeting rapid changes in heat treating technology and customer requirements.

###### 橡皮秤
橡皮秤,又称密尔秤、密尔胶称重物件,是利用橡皮应力原理进行物体质量测量的仪器。结构简朴,精度可靠,方便快捷,极易测量钢材、有色金属、非金属材料的质量大小的仪器。它的秤片上带有活动的橡皮圈脚,可进行灵活的多尺秤重。当量物时,秤片部位的外加力q越大秤片越凹,秤片变形量越大,称内质量轡值略有变化。可能是由波贝秤派生出来的。具有简易、好操作和量重精度高的优点

中给出了强化温度。什么是强化温度?
强化温度是热处理过程中影响材料性能特性(包括强度和硬度)的参数。此温度应低于结构材料的晶粒细化温度,同时低于析出变结构的那些重要对象的阶段相变点。 非金属的强化温度本质上是热处理过程中材料受热后表面层形成微缺陷的温度。
