Tempering + quenching

Tempering + quenching

Tempering + quenching

(OP)
Hola

If I was native English speaker, I for sure wouldn't need to open this topic. Actually I have simple question. I search for engineering term. The one that is meant as process of thermal/heat treatment and according to google, which I believe is for sure correct, the description of this term is:

"Tempering plus quenching"

What is this? Its well-known process, everyone knows it and so do I but unfortunately just in my native language. I search for correct engineering english term.

The process name that I search for is different than tempering, carbonitriding and cementation. But they are all (including that one for which Im asking) thermal/heat processes.
I haven't found the full list of thermal/heat processes so I cannot find it myself.
I know the question might be a bit funny, and the process whos term I search might even be the most known process of all in thermal/heat processes but I checked my dictionaries and cannot find the correct english term for it.
For sure its not "annealing" or "hardening", neither just "quenching".
To be even more specific which term do I need; Im asking for the process which is (probably) combination of quenching (=annealing?) and tempering. The process is used for steels who usually have between 0,3 and 0,6% of carbon. Hardness of material is increased because of containing steady carbides and ductility is increased.

Also; Did I say correctly, its "cementation" and not "cementing", right?

Looks like I will need to search for a better dictionary.

RE: Tempering + quenching

The usual term in North America is "quenching and tempering".  Standards such as ISO 4885 and EN 10052 specifically define "quench hardening" and "tempering" and ISO 15787 shows how to specify this type of heat treatment on engineering drawings.  Here is an example:

quench hardened and tempered
59 + 4 HRC


Here is a link to EN 10052 where you can see the exact definitions:

RE: Tempering + quenching

(OP)
If I use the term "quench hardening", can this be also named as "austempering"?
Of course quench hardening / quenching and tempering / austempering (?) is different process compering to tempering.

RE: Tempering + quenching

No. Austempering is a different process and will result in a different metallurgical structure.

RE: Tempering + quenching

As swall said, austempering is not the same as quench hardening.  In the link that I provided, there are separate definitions for austempering and quench hardening.

RE: Tempering + quenching

The way PersonXY is asking the question suggests he  asking for  the austenizing heat treatment (austenizing from the link)  and then quenching the steel to form martensite. Rather than the heat treatment after quenching.
