I have read that 9260 spring steel was a form of 1060 steel treated with a silicone alloying agent to give it that flexibility seen in Cheness katana. My inquiry is, could such an alloying agent be used with other types of steel? Like 1045 of something similar. Man At Arms Reforged on Youtube said something along the lines of 1045 being good for large styles of blades because it's more forgiving if done properly. Would a silicone alloyng agent make 1045 in 9245? I am curious because in theory you could make large style blades with increased felxibilty. Not knowing much about metallurgy I figured it best to post my question here.
So, is it possible, feasible, or just not worht the effort?

Primary characteristics of 9260 are the presence of (most notably) silicon but also manganese.
As opposed to 5160 which is Chromium and Manganese (also silicon and phosphorous but to a lesser degree).
Both are .6 or so carbon so yeah your logic holds... sort of...
But i’m not sure Men at Arms is correct that a 1045 is better for large blades... 1.) heat treatment matters most. 2.) plenty of good and large blades made from 5160 and 9260...
Maybe their argument was sort of leading towards toughness over hardness? Albion for example uses 6150 which is sort of what they are getting at... though the 61XX series throws in the Vanadium but has alloying mixed of the Chromium, manganese ans silicon closer to that of 51XX.

I think 1045 is mostly forgiving in the forging, not so much the use of the sword

silicone and silicon are two very different things.

Doesn't silicon make your sword grown bigger. Think I enjected silicon into the tip of this one.

You certainly don't want to mix those two up if you earn a living as a cosmetic surgeon. I know that silicon (not silicone ) in steels is used to deoxidise the steel, reducing localised defects. Also acts similar to manganese (increasing tensile strength and hardenability) but to a lesser extent.

Very simplifying answer: Si increases toughness in/after heat treatment, but 1045 is already very tough, because with its lower carbon content it can't be heat treated very hard and brittle anyway. So it's not worth the effort.
