Check Reports -> Organizations -> Airforce/Military Council (depending on who is doing the research) and there's a breakdown of how they invest their Bureaucratic Points (BPs). The Research entry should tell you how many BPs they get per turn, how many they still need, how many they have invested so far and how many BPs is each 1% of progress worth.

Check to see that your budget (National and the specific Council) is allowing enough BPs to flow to Research. Don't just look at the percentages, look at the actual numbers as I have outlined above. Also, make sure you are actually researching Lightweight Alloys and hadn't dropped it for some different tech earlier.

Manual

5.13.1.2. Linear Techs
Some Techs are Linear Techs. They become useful from the first point of
progress you have made on them and provide a bonus to something. The
higher your progress the higher the bonus. They can be discovered and
researched by your Applied Science Council.
Linear Tech costs X BP per point, but the higher you get the more expensive
it will get. At 25 points the cost will have almost doubled and at 50 points
it will have quadrupled. At 75 points it will have increased sixteen-fold. 100
will be near impossible to reach.
