  1. That's a good question, and I'm not sure. Per the spec sheet N-L-M posted, it is a solution hardening (which is the same thing as "age hardening;" metallurgical terminology is nonsense sometimes) alloy. I bet that small titanium addition is what's doing the trick. So the precipitation hardened part could be reset. However, it also has a bit of carbon in it, unlike a lot of other maraging steels. If you tried to "reset" the heat treatment, that carbon could cause some problems. Some carbides form at higher temperatures than the intermetallic precipitates, and if the metal is ho

  2. You didn't read all of that guy's comments, even: "The whole story was blown out of proportion in subsequent german tertiary reception of the action, most likely due to inaccurate descriptions and lack of access to source documents. Someone started putting the whole units claim incorrectly to Körners credit and then kept on adding whatever Harrer, Diers, Schäfer, Turk, Müller et al. claimed on their own on top to arrive with a new unit claim. And instead of "for no losses", I have hard evidence to confirm that four TIGER Ausf. B were total write offs on this day (two caught by arti

  4. While this is true, the solution heat treat is above that temperature, and everything should dissolve. Forming the wrong precipitates is an issue if you age wrong or if you accidentally age via heat input such as welding later in the process. welding itself is also an issue for precipitation hardened metals if done post-age as it remelts the HAZ had effectively solutionizes it, of course. This is what causes 6061, for example, to lose so much of its strength in the HAZ.

  5. Don't hold me on this but as far as I know, there was a picture of a brochure of DM53 posted sometime in the past on the net where it said the penetrator body was 685mm though I don't remember if it also said anything about the diameter; Regardless of this, i think comparing DM53 to Type 10 AFPSDS is a bit of a moot point and it would do us better to compare DM53 to M829A1/2 which both have 680x22mm and 690x22mm penetrators respectively in a projectile body roughly ~760mm long (though it's 779mm long in total). There's also the case of yet another, I believe Rheinmetall

  6. I wonder what's the point of this obsession with propaganda-driven made-up stats of several individuals leaving the other millions of common German soldiers looking like a useless inept crowd. That applies twice more if those individuals are hardcore nazi from SS. That's not only weird but also rather sick fetish.

  7. Ah yes, "hit by projectile" a surefire way to determine the cause of destruction to be the 'long 8,8' since that thing is unique in the sense that it's the only thing on the battlefield that fires projectiles! The rest of the guns fire... what exactly?

  8. My primary reason for this is the fact that its got a proper diagram with listed lengths which is pretty hard to come by past DM33. It acted as essentially a control group to make sure I was doing proper measurements. However after cross checking with your measurements I can't find any fault in your measurements either despite them being different from mine and I have a few guesses as to why. Here is the first one. When measuring I was measuring from tip to ends of the fins. I found a diagram of 105mm Type 93 to compare against the Type 10 as there was no indication for either m

  9. You're ignoring the part where critical mass founds his argument on the Soviet losses of that entire part of the front for that day, then elides his way into the two numbers being similar and that therefore Korner's account is somehow legit. Peter goes into this at length.

  10. 27 degrees or 27% (15 degrees) gradient? If it’s a 27 degree gradient, that’s actually pretty good. Modern western AFV generally can do 60% (31 degrees), so 35 degrees (70%) is very, very good.
