Good starter metallurgical microscope?

I want to look at opaque objects under a microscope, like computer components and stuff. I assume the type of microscope I would want for that is a compound metallurgical one since that's what they're for, right?

As far as zoom, I would want to see as much as I can without needing an oil drop

Looks like the cheapest one AMScope has is almost $900. Is there a reason they're so much more expensive than regular compound microscopes?

Is 'pressure testing' actually a final metallurgical processing step?

Elon has made a couple of interesting comments about stainless steel properties, most notably how cold forming increases it's strength. The statement that caught my attention specifically was during the everyday astronaut interview. The context suggested it was part of the manufacturing process for the tanks. So, is SpaceX using the pressure test as a method of cold forming the steel?

Canada Nickel Continues to Demonstrate Significant Improvements in Metallurgical Performance at Crawford Nickel Sulphide Project $CNIKF

Further to my ongoing due diligence on Canada Nickel (OTCQB $CNIKF) (CSE $CNC) (FRA $4E0), below is a news release that could be considered a company catalyst:

Canada Nickel Continues to Demonstrate Significant Improvements in Metallurgical Performance at Crawford Nickel Sulphide Project https://www.prnewswire.com/news-releases/canada-nickel-continues-to-demonstrate-significant-improvements-in-metallurgical-performance-at-crawford-nickel-sulphide-project-301435775.html

Canada Nickel today announced further results of metallurgical testing at its Crawford Nickel Sulphide Project that continue to demonstrate significant improvements in metal recoveries relative to the Preliminary Economic Assessment ("PEA").

… The sample was selected from the South Low Grade region of the Crawford Main Zone and achieved a nickel recovery of 61%, which is 19 percentage points higher than what was modelled for this type of sample in the PEA.

… The nickel concentrate grade of 37% is 2% higher than our target 35% grade for this product and highlights the Company's ability to produce the one of the highest grade concentrates on the market.

Highlight(s)

  • Achieves 61% nickel recovery and produces 37% nickel concentrate from lower grade sample of 0.22% nickel and 0.08% sulphur
  • Nickel recovery 19 percentage points or 45% higher than the PEA model
  • Iron recovery of 63% was 15 percentage points or 31% higher than the PEA model

Management Comment

>"These metallurgical testing results continue to demonstrate the potential from our flowsheet optimization program to deliver improvements in recovery well in excess of the 4-5 percentage point improvement that we are targeting for our feasibility study. Each percentage point improvement in nickel recovery would yield a US$92 million improvement in the value of the NPV8% of the project, based on the PEA metrics. While we continue to expect a broad range of recoveries from the samples which will be tested during the variability program, the ability to achieve 60+% recovery from samples from the lower grade portion of the resource is an excellent outcome."
