Reynolds 853 and X100 (1 Viewer)

[strida]

does anyone have any information including the:

• strengths
• fatigue resistance
• resistance to bending
• ease in which they can be joined

of each of these materials iam soo stuck cant find anythin on the net about em

the problem is the metal is proprietary, so it tends to be abit harder to find information readily about the metal tubing products. Anyways....

x100
this is new form of aluminium

its basically airhardened steel

Alumimium x-100
UTS : 550-600 MPa, density 2.65 gm/cc

Derived from aerospace projects, and used for custom build bike projects.When added to aluminium, lithium can increase the strength and stiffness while reducing density. High tensile strength with good fatigue resistance make this alloy suitable for super-light frames after full frame heat-treatment.

This alloy was derived from work on the Space Shuttle propellant tanks but is now has limited production availability.

Steel 853

AMLESS AIR-HARDENING HEAT-TREATED STEEL

UTS: 1250-1400 MPa, density 7.78 gm/cc

The benefits of an air-hardening steel are particularly noticeable in the weld area where, unlike conventional steel alloys, strength can actually increase after cooling in air immediately after welding. This feature is a result of the fine grain structure due to the chemical compostion specified. 853 is heat-treated to give high strength and damage resistance.


hope that helps ..based on the bit of info provide it should make it abit more easier for you to expand on each materials properties..

Cheers boys

 

[makeHSChistory]

oh yeh i actually have no information for you.
good luck

 

[hello-there]

i also need some info concerning this topic
thanx for the info Monnie

 

[fullonoob]

lol this is the copeland engineering report.
anyone actually finished it yet?
post here

My report is uploaded on the website

Note: some of the stuff in it is bullshit, be carefull if you have a really cluey teacher

lols one of the students in my school is handing in your direct report :mad1:
Pretty bs though, he said he cbf changing it...plagiarism to the max for hsc GG. I've used your report for a lot of referncing though, added you in the acknowledgement section too :uhhuh:

Note: No it is not me.

200th post yay xP

Really what a dick. Dont worry too much though about his mark, even if he beets you in this i guarentee he will do bad in the exams. Thanks for the rep haha. I would post my crane hook one up, which is form the lifting devices mod, but the site wont let me. So give me your email and i will send it to you =)

I think its the best of my three reports

If you still have the report could you please send it? Engineering has pretty much stayed the same in the HSC for almost 20 years. I would appreciate if you could send it.

Reynolds 853 is a low-carbon steel alloy containing manganese, chromium, molybdenum, copper and silicon. 853 tubes are manufactured in very thin wall thicknesses, like 0.5 mm to 0.4 mm. They are weldable by conventional tungsten-inert-gas (TIG) welding and gas-metal-arc-welding (GMAW). Tubes are seamless (no joints) and cold worked to increase the tensile strength by work-hardening. Reynolds 853 tubes are also available in the quenched and tempered condition.
The resistance to bending of a steel tube is a function of the Ultimate Tensile Strength (UTS) and the geometry of the tube (diameter, wall thickness and ovality).
There is only so much that the tube manufacturer can do to reduce fatigue cracking. Fatigue resistance of steel bicycle frames is a function of the quality control exercised during frame manufacture, in particular elimination of any sharp corners or notches that act as stress raisers, careful blending of welds, and double-butting of tubes so that extra thickness is provided at the joints where it is needed most. Reynolds 853 tubes are double-butted.
The chemical composition of Reynolds 853 is fine-tuned to the rapid thermal cycle of TIG welding to produce an austenite to bainite phase transformation in the heat-affected zone (HAZ) upon cooling between 800^oC to 400^oC. This ability to air-harden in the HAZ gives frame builders an economic advantage, and removes the need for any subsequent heat treatment.
Here is a chart taken from Reynolds website comparing the mechanical properties of their products. Notice that the stiffness (Young's Modulus) of steel alloys are all the same. That is because Young's Modulus is determined by the iron content and not by the alloying elements or the heat treatment.

Thanks, the info on welding helped out quite a bit.
