Prensado isostático en caliente. El prensado isostático en caliente (Hot Isostatic Pressing, HIP) es un proceso de fabricación utilizado para reducir la porosidad de los metales y la influencia de la densidad de muchos materiales cerámicos.
Esto mejora las propiedades mecánicas del material y la viabilidad. Procedimiento[editar] El proceso de prensado isostático en caliente somete a un componente a la vez a elevadas temperatura y presión de gas isostática en un recipiente contenedor de alta presión.[1] El gas de presurización más utilizado es el argón. Se utiliza un gas inerte, de manera que el material no reaccione químicamente. La cámara se calienta, haciendo que la presión dentro del recipiente aumente mucho. La temperatura se puede elevar hasta 3000ºC mediante calefactores de grafito.

Here are my top ten words, compiled from online collections, to describe love, desire and relationships that have no real English translation, but that capture subtle realities that even we English speakers have felt once or twice.
As I came across these words I’d have the occasional epiphany: “Oh yeah! That’s what I was feeling...” Mamihlapinatapei (Yagan, an indigenous language of Tierra del Fuego): The wordless yet meaningful look shared by two people who desire to initiate something, but are both reluctant to start. Oh yes, this is an exquisite word, compressing a thrilling and scary relationship moment. It’s that delicious, cusp-y moment of imminent seduction. Yuanfen (Chinese): A relationship by fate or destiny. From what I glean, in common usage yuanfen means the "binding force" that links two people together in any relationship. But interestingly, “fate” isn’t the same thing as “destiny.” Retrouvailles (French): The happiness of meeting again after a long time. Los mejores inventos del 2011. Cygnet Engineering. Interactive. The World of Seven Billion The map shows population density; the brightest points are the highest densities.
Each country is colored according to its average annual gross national income per capita, using categories established by the World Bank (see key below). Some nations— like economic powerhouses China and India—have an especially wide range of incomes. But as the two most populous countries, both are lower middle class when income is averaged per capita.
