This article discusses the post weld heat treatment (PWHT) process and its effectiveness in reducing the residual stresses and improving the mechanical properties of weldments.
The properties of alloys can be further improved through heat treatment to meet various needs. In this article, we will look at how heat-treating AerMet100, a steel alloy, impacts its properties.
This paper focuses on the interactions between peripheralization, vulnerabilities of agricultural livelihoods, and local collective agency in the creation of new capabilities in intermediate cities. It discusses the theoretical implications of a study conducted in the municipality of Tarímbaro, part of the intermediate city of Morelia, Mexico; it expands on results already published in preliminary form. The unit of analysis was the ejido, since this type of social land tenure, granted to landless peasants in 1917 after the Mexican Revolution, is one of the most important forms of social organization in rural Mexico. About one-half of the Mexican territory comprises >30,000 community-based land tenures (mainly ejidos), and a high proportion of the land now occupied by urban centres was ejido land. This paper uses the example of fifteen ejidos, notably affected by the expansion of Morelia city, to illustrate how local (rural) organizations can foster collective agency to reduce d
